I think it's in IP1, it shows "in progress" instead of "we are processing".
Maybe I can share some bits of my timeline.
01 Aug 2020 - AOR
19 Aug 2020 - ADR for IMM5475 -> I believe the R10 check completed at this point
20 Aug 2020 - BIL and MEP
21 Aug 2020 - I gave my biometrics (VFS was pretty empty and I was so excited that I booked the appointment the day after BIL)
I also uploaded my ADR on 19 Aug 2020. I noticed that the Additional Document message was changed to "We are reviewing your additional document..." almost immediately
10 Sep 2020 - Ghost Update. There are 2 messages that were updated, actually.
Additional Document - Not Applicable
Background Check - Your application is in progress. We will... (the so-called IP1)
01 Oct 2020 - I managed to contact an IRCC agent and was informed that my file had been transferred to the Singapore VO.
05 Oct 2020 - Ghost Update.
Background Check - We are processing your background check... (the so-called IP2)
